We have synthesized and electrochemically tested carbon samples that a
re suitable as anodes for lithium secondary batteries. The unique synt
hesis is based on the use of the inorganic templates and organic precu
rsors. Pyrolysis of these carbons was performed at 500 and 700 degrees
C. High reversible capacity (up to 825 mAh/g) was found on samples he
ated to 700 degrees C. The cells were tested continuously for more tha
n 20 cycles with a drop in capacity of only 10%. X-ray powder diffract
ion showed that the samples heated to 700 degrees C have a highly diso
rdered structure.
